Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484156, here are decompositions:

13 + 31484143 = 31484156
97 + 31484059 = 31484156
199 + 31483957 = 31484156
229 + 31483927 = 31484156
337 + 31483819 = 31484156
349 + 31483807 = 31484156
367 + 31483789 = 31484156
397 + 31483759 = 31484156

Showing the first eight; more decompositions exist.
